Many people say they want to reduce body fat, have tried exercising, and have adjusted their diet, but it hasn't worked well. One reason for this could be an approach that fails to consider gender differences. Because men and women have fundamentally different hormonal structures, the locations where body fat accumulates, the order in which it decreases, and effective strategies can all differ. This article organizes more practical body fat reduction directions based on the physiological characteristics of each gender.
You Need to First Understand Why Men and Women Have Different Body Fat
It's easy to think that you only need to exercise hard to reduce body fat. However, even when men and women do the same exercise at the same intensity, the results often differ significantly. This is not a matter of willpower or effort, but rather the fact that the biological starting point itself, called hormones, is different.
According to data from Kormedi.com, the healthy body fat percentage range for ages 20-39 differs structurally: approximately 8-19% for men and approximately 21-32% for women. This is because male testosterone acts to increase muscle synthesis and basal metabolic rate, while female estrogen acts to store energy in the form of fat. Clinical data confirms that this difference in sex hormone environment has meaningful effects on body fat distribution and metabolic rate.
Without understanding this difference, if you simply follow the same diet and exercise, the reduction speed or response pattern may differ from expectations. Even if you reduce the same calories and exercise for the same amount of time, results will appear differently. For this reason, body fat reduction strategy should start with first understanding the gender hormone environment.
💡 Mini Q&A
Q. Why is the body fat percentage standard different for men and women? Women's bodies are designed to require a certain level of body fat for physiological functions such as pregnancy and breastfeeding, so even with the same body shape, the healthy body fat percentage standard is set higher for women than for men.
How to Reduce Body Fat for Men — Approach with a Muscle Advantage Strategy
Men have a higher basal metabolic rate than women due to the influence of testosterone and a favorable environment for muscle synthesis. By utilizing this characteristic, you can approach body fat reduction more efficiently. The key is to place strength training first and aerobic exercise second in a complex exercise sequence.
According to research published in the Journal of Exercise Science & Fitness reported by Kormedi.com, the group that performed strength training first showed a decrease in body fat of approximately 4% and visceral fat of approximately 5%, while the group that did aerobic exercise first saw decreases of approximately 2% and 3% respectively. This means that just changing the order of exercise can create differences in visceral fat reduction effects.
Here is a checklist for practical implementation of male body fat reduction:
— Prioritize strength training, follow with aerobic exercise: Place aerobic exercise after weight training to increase fat burning efficiency.
— Check protein intake: To maintain muscle mass, protein intake of approximately 1-1.2g per kg of body weight may be helpful.
— Intensive visceral fat management: Men have higher visceral fat risk in the abdomen than women, so it's good to monitor changes in waist circumference together.
— Adjust reduction speed: According to a statement by Professor Park Jung-hwan from the Department of Endocrinology and Metabolism at Hanyang University Hospital, excessively rapid weight loss tends to cause yo-yo effects, so a speed of approximately 0.5kg per week is recommended.
— Avoid extreme calorie restriction: If you reduce calories too much, muscle may break down first. The balance between appropriate dietary control and exercise is important.
Related clinical data shows that a combination of at least 150 minutes per week of moderate-intensity aerobic exercise and strength training at least twice a week is the recommended direction for body fat management. Rather than pushing your body to extremes rapidly, the key is to create a routine you can maintain consistently.
How to Reduce Body Fat for Women — You Should First Examine Hormone Balance
The reason why body fat reduction feels more difficult for women than for men is not a matter of willpower, but rather a clear reason: the difference in hormone structure.
According to NCBI (PMC6997275) research, the female body is evolutionarily designed to store energy in the form of fat, so even in the same caloric deficit state, fat reduction speed may appear slower than in men. Added to this is the fact that hormonal fluctuations are more significant due to menstrual cycles, pregnancy, menopause, and other factors.
Data from Kormedi.com also explains that as estrogen decreases in menopausal women, fat tends to shift from the buttocks to the abdomen, which increases the risk of visceral fat and metabolic diseases. Additionally, it is known that if a woman with unbalanced female hormones repeatedly engages in starvation diets, her metabolism can deteriorate more quickly.
The table below summarizes the differences in body fat management approaches between women and men.
| Item | Men | Women |
|---|---|---|
| Main Hormones | Testosterone | Estrogen, Progesterone |
| Fat Distribution | Abdomen, visceral focus | Buttocks, thighs → abdomen after menopause |
| Reduction Speed | Relatively fast | Relatively gradual |
| Recommended Exercise | Strength first + aerobic second | Strength training + intensity adjustment considering menstrual cycle |
| Dietary Strategy | Protein intake + appropriate calorie restriction | Nutrient composition considering hormone balance |
| Precautions | Intensive visceral fat management | Avoid starvation diets, be cautious of metabolic decline |
For women, rather than simply eating less and moving more, managing lifestyle habits suited to their constitution and hormone environment may be more helpful for sustainable weight loss. Gangbuk Anjeong Korean Medicine Clinic diagnoses individual constitution based on 8 Constitution Medicine and provides customized guidelines for eating habits and lifestyle habits. We carefully examine constitution-based management for women whose hormone environment changes frequently.
Before Reducing Body Fat, These People Should Check First
If you're exercising and following your diet but your body fat isn't decreasing, it's necessary to check your overall lifestyle. There are various factors that can hinder body fat reduction aside from lack of exercise or overeating.
According to data from Ilsan Hospital of the National Health Insurance Service, when chronic stress persists, excessive cortisol secretion can occur, which can lead to decreased muscle strength and increased fat. In other words, stress itself can create an environment that promotes body fat accumulation.
Also, according to a report from Lady Kyunghyang, regular sleep of 7-9 hours daily is known to help maintain hormone rhythm and suppress excessive cortisol secretion. When sleep is insufficient, appetite-control hormones become unbalanced, making weight management even more difficult.
Check the following items yourself:
— Sleep is irregular or less than 6 hours on many days — Work and home stress have become chronic — You skip meals or reduce your daily caloric intake excessively — Your weight has changed drastically in a short period — You repeat only aerobic exercise without strength training
As stated by Professor Park Jung-hwan at Hanyang University Hospital, excessively rapid weight loss carries the risk of muscle loss, nutritional imbalance, and decreased energy. Clinical data also points to rapid fasting as a factor that lowers basal metabolic rate and causes yo-yo effects. For this reason, stabilization of lifestyle habits should precede weight reduction.

Reducing Body Fat — Were You Curious About These Points?
Q1. Is it true that men lose weight faster than women?
Generally, men have higher basal metabolic rates and greater muscle mass due to testosterone, so initial weight loss often appears faster. On the other hand, women tend to have a more gradual reduction speed because estrogen directs fat storage. It's only a difference in speed; women's fat reduction isn't impossible, so it's important to choose a strategy suited to each gender's characteristics.
Q2. Should women exercise during their menstrual period?
It's not necessary to stop exercising completely during your period. However, during times when conditioning is reduced, such as days 1-2 of menstruation, adjusting to light stretching or walking at reduced intensity places less burden on the body. Being aware of physical changes according to the menstrual cycle and flexibly adjusting exercise intensity is helpful for consistent management.
Q3. Is it okay to just do aerobic exercise to reduce body fat?
Aerobic exercise helps with calorie expenditure, but if you repeat only aerobic exercise without strength training, muscle mass also decreases, lowering your basal metabolic rate. When basal metabolic rate drops, over time the same amount of exercise will make body fat harder to lose. Combining strength training and aerobic exercise is a more effective approach for sustaining body fat reduction.
Q4. Doesn't body fat decrease if you starve yourself?
While body weight may appear to decrease in the short term, extreme fasting can work by breaking down muscle before body fat. When muscle decreases, basal metabolic rate drops, and when eating resumes, yo-yo effects appear more easily. For safe reduction, maintaining appropriate nutrient intake while gradually reducing at a pace of approximately 0.5kg per week is recommended.
